[R] Calling R from within C++ examples?

[James Allsopp]

Hello,
I was wondering if anyone had an example of using C++ to call routines
from within R. What I want to be able to do is call the dip routine from
the diptest package. I've tried using the code from the package
directly, but I think it needs to have had other procedures to be run on
the data before-hand.

Any ideas as I'd be very grateful.
James
